·Winds of 30-60
kph may be expected in at least 36 hours or intermittent rains may be
expected within 36 hours. (When the tropical cyclone develops very close
to the locality a shorter lead time of the occurrence of the winds will be
specified in the warning bulletin.)

·A tropical
cyclone will affect the the locality.

·Winds of
greater than 60 kph and up to 100 kph may be expected in at least 24
hours.

·A tropical
cyclone will affect the locality.

·Winds of
greater than 100 kph up to 185 kph may be expected in at least 18 hours.

·A very intense
typhoon will affect the locality.

·Very strong
winds of more than 185 kph may be expected in at least 12 hours.

It is Important to note that when any Public
Storm Warning Signal Number is hoisted or put in effect for the first time, the
corresponding meteorological conditions are not yet prevailing over the
locality. This is because the purpose of the signal is to warn the impending
occurrence of the given meteorological conditions. It must be noted also that
the approximate lead time to expect the range of the wind speeds given for each
signal number is valid only when the signal number is put in effect for the
first time. Thus, the associated meteorological conditions are still expected in
at least 36 hours when PSWS #1 is put in effect initially; in at least 24 hours
with PSWS #2; in at least 18 hours with PSWS #3; and in at least 12 hours with
PSWS #4. The lead time shortens correspondingly in the subsequent issues of the
warning bulletin when the signal number remains in effect as the tropical
cyclone comes closer.
